I have upraded my monitor for a 30" 2560X1600 , My graphic card is a Gigabyte 660ti oc 2GB.
Now i need to upgrade the videocard for better performance...For budget reasons I will go in SLI mode. I will get a second 660ti oc, but for about 50$ more i can get a Gigabyte 770 OC 2GB this one give better performance...Can i pair a GTX660ti with a GTX770oc or I have to stay in the 600 series ?

My PC spec:
Operating System: Windows 8 Professionnel 64-bit

Nope, the two cards in SLI need to have the same GPU!

Need more answer because one say NO and one say YES

Same GPU...like Kepler? (660ti and 770 use Kepler)

You must use the same card. If you were able to put a faster card in, the speed of the faster card would be slowed to match the speed of the slower card anyway, so you wouldnt gain anything even if it would work. I just toss that out there because there are some cards of the same family gpu that can work together even though the cards may be different in core speeds, memory size and/or speed.

A 660Ti will only SLi with another 660Ti, not a 660 non Ti or a 770 or a 780 only another 660Ti.

We're both saying no. I don't know about using diferent manufacturer card, but to be in SLI they both have to be the exact same card. EX: Two 660

Nvidia send me and reply to my email, sending me to link on their forum...I leave the answer here i case others like to know:

Take from Nvidia:

- All graphics cards must have an identically named GPU
(This means the simplified model name for the GPU. An EVGA GTX480 Hydro Copper FTW Edition is simply a GTX480 in terms of SLI.)

-- You can only SLI together an Identical GPU with identical GPU. GTX680 with a GTX680. GTX560 with GTX560. 8800GT with 8800GT. Etc.

The only exceptions to this rule are the 9800GTX, 9800GTX+ and GTS250, which can work in SLI with each other - assuming the other requirements are met.
Note: Be careful with the extensions on GPUs. The extensions denote a totally different GPU. EG the GTX460SE and GTX560Ti are not SLI capable with the GTX460 and GTX560 respectively.
IT IS EXTREMELY IMPORTANT TO CHECK THIS WITH THE GTX460 - THERE ARE 4 VERSIONS OF IT (GTX460 1GB / GTX460v2 1GB / GTX460SE 1GB / GTX460 768MB)! THE SAME VERSION IS REQUIRED FOR SLI!


- All GPUs must have the same amount of VRAM and an identical Bus Width
-- You cannot use a "256MB" version with a "512MB" version or "1GB" version with a "2GB" version in SLI or a 1GB 192 bit bus with a 1GB 256 bit bus Etc.
Note: It used to be possible to enable SLI on cards with differing VRAM (EG 8800GTS 640 and 320) via the "coolbits" mod. However, this mod will not work with newer cards or newer drivers.


- An SLI Bridge
-- You need to use the correct SLI Bridge for all SLI, 3-way, 4-way and Quad SLI configurations.


- Only one type of SLI card team per system
-- You cannot have 2 different pairs of cards in SLI in the same system. (EG 2x GTX285s + 2x 9800GTXs)
Note: Using two EVGA GTX275 Co-Ops (or similar multi-GPU cards) falls under this category. The GTS250s will be unable to be used in SLI in tandem to the two GTX275s.


- OEM system exceptions
-- On some OEM systems (Dell / Alienware in particular) you may be unable to SLI the existing OEM graphics card with a standard retail version of the card due to graphics card or motherboard BIOS restrictions.
Note: This issue is particularly present with Dell GTX260s and GTX460s.
